600W (±24V Main Voltage) LLC Switch Power Supply Module Dual Power Supply for Power Amplifier
Description:
- Fixed pulse width output, no variable pulse width clutter interference of the hard switching circuit, the no-load switching frequency is greater than the resonance frequency, the heavy-load switching frequency is equal to the resonance frequency, and the standby power consumption is relatively low. The secondary output of the transformer is a pure square wave, and the waveform at both ends of the resonance capacitor is a sine wave, so the current waveform is also a sine wave! Minimal interference to other electrical equipment, very suitable for power amplifier products!
Specifications:
- Input: AC200-240V 50/60HZ
- Auxiliary power supply: dual 12V 0.5A (main voltage and auxiliary voltage are not common ground, completely isolated)
- Conversion efficiency: 90 - 95% (The higher the output main voltage, the higher the efficiency)
- Ripple: about 0.3% (peak value)
- Shell size: 130 x 88 x 45mm
- Net weight: about 0.39kg
Features:
- U-shaped housing which also has the role of radiator.
- The output terminal, except for the screw, adopts a copper foot high current terminal.
- With undervoltage, overvoltage and overcurrent protection! It is suitable for various power amplifier boards within the driving parameter range, typical application drive and digital power amplifier boards which adopt TDA8954, IR2092 and other chips.
- Low price, light weight, high efficiency and wide working range.
- Adopt imported PWM chip, imported high-power field effect tube, imported fast recovery diode, for Samsung chip capacitor and Seiko U-shaped aluminum heat dissipation.
Package Included:
- 1 x Switch Power Supply
Precaution:
- Please ensure that you have a certain foundation in electronic technology. There is high voltage mains power on the input components of the power module. Please pay attention to safe operation! When the output voltage is higher than the safe voltage of 36V, please pay attention to your own safety protection. We are not responsible for any other consequences or losses caused by blind operation!
- It is a switching power supply designed for power amplifier use, and its heat dissipation design is based on the power amplifier use. It is prohibited to use it for other purposes. We are not responsible for damages caused due to blind use in other situations.
- It is normal for the output voltage to jump slightly under no-load conditions. This is because the no-load chip is working in intermittent power on mode, which is completely normal.
- Auxiliary power supply: ±12V 0.5A (main voltage and auxiliary voltage are not grounded and completely isolated). The switch power supply mainly controls the main voltage. The auxiliary voltage must be used when the main voltage is under a certain load. If the main voltage is unloaded, the chip will consider that the output voltage of the switch power supply has arrived and will turn off the chip. It is not allowed to use only the auxiliary part without the main voltage.
